Since their coming into being， automobiles have been significantly contributing to human industries， agricultures， and even the daily lives.
It is automobiles that have been shaping and reflecting the ways humans work and think. They accelerate the sustainable economic development. They boost industries. They also catalyze scientific research.
But nobody can deny that automobiles have also exerted some unfavorable impacts on social and economic fabric. First of all， they have seriously polluted the environment in which humans survive. Secondly， traffic jam wastes lots of time. Finally， they also waste the money， especially in metropolis.
My opinion is that in the foreseeable future， scientists will be able to solve all problems. Exactly， human will eventually be able to minimize the harmful effects of automobiles， whereas their advantages can be maximized.
你如何看待出国留学的利弊on overseas study
[参考范文]on overseas study
Recent years， more and more Chinese people have chosen to study abroad. To this tendency， some people think it is not good， as most of the overseas learners do not come back， whereas I hold a different opinion.
In my opinion， it is a good thing that more Chinese people go abroad. There are three reasons. First， the overseas learners can improve their ability through the study. They can grasp advanced technologies and their language ability can be improved as well. Second， with the rapid development of China， more and more overseas learners will choose come back， using their abundant knowledge studied abroad to serve for the motherland. The third， the government and most domestic enterprises are willing to provide favorable treatments to attract them to come back.
Although some do not want to come home， we are glad to see that there are more overseas learners chosen to work at home than before. For the above reasons， I think it is not a bad thing for more and more Chinese study abroad.
